Triager log/How to become a triager

Currently we have:

• a developer log
• an how to become a core developer pages

As far as I know, there is no equivalent to the developer log for triagers, and there is a section about becoming triagers.

I think we should:

• Add a triager log (possibly generated by the file proposed in #848)
• Add a link to the "becoming a core dev" page to the "becoming triager" section, or move both to the same page
• Improve the documentation on how to become a triager, including steps such as
  • making an official announcement on Discourse
  • adding the new triager to the triagers team on GitHub
  • reclaiming the GitHub mannequin
  • join the Discord server
• Add links between the developer/triager logs and the "becoming *" section and the other way around

Bắt đầu bằng cách đọc các trang developer log, core developer và triaging được liên kết trong issue, sau đó xem lại tệp được đề xuất trong #848. Công việc được coi là hoàn tất khi triager log tồn tại, becoming-triager guidance bao quát các bước onboarding được liệt kê và các trang liên quan liên kết đến nhau.
